THE GEOTECHNICAL INVESTIGATION FOR THE PROPOSED

GRADE SEPARATOR

REPORT ON THE GEOTECHNICAL INVESTIGATION FOR THE PROPOSED FLYOVER

INTRODUCTION

The primary objective of this investigation is to establish the geotechnical condition at the site and to evaluate the bearing pressure and other engineering design parameters through the various field and laboratory tests. This report consists of the details about the field tests performed and the recommendations made based on the results of the tests.

SCOPE

The scope of work includes both the field and laboratory tests. Two boreholes by rotary drilling method are planned to obtain the sub-surface stratification. Fig.1 shows the location of the boreholes on the entire plan of the proposed construction site.

of 71


FIELD INVESTIGATION

Boring and Sampling

150 mm diameter boring at all places is carried out in accordance with IS: 1892 -1979 Code of Practice for sub-surface investigation of foundation (1992) by adopting auger boring. Representative I undisturbed samples are collected at different depths as the boring operation progressed. Various laboratory tests are conducted on the samples collected. Standard penetration tests are conducted at every 1.50m interval as per IS: 2131 - 1981.

Field testing

(a) Standard penetration test

Standard Penetration Test (SPT) is carried out at different depths in all the boreholes & the 'N' values are recorded. The number of blows required to drive a 50mm diameter split spoon sampler for a depth of 30cm using a 65 kg hammer for a drop of 75cm is recorded as 'N' value. The results of all the penetration tests are performed in each of the boreholes and they are shown in their respective Bore logs. The test is halted if,

i) 50 blows are required for any 300mm penetration.

ii) 10 successive blows produce no advance and the N - value is recorded as "REFUSAL"

LABORATORY TESTS

Laboratory tests are performed to evaluate both the index and engineering properties of the soil samples collected during boring. The different tests performed are grain size analysis, determination of Atterberg limits, moisture content and shear tests. The results of these tests are presented in tables I to 2.

SUB SOIL PROFILE

The subsoil generally consists of top nil to an average of 1.25m is filled up soil followed by yellowish red /whitish grey fine sandy silt up to 3.0m depth. Below this depth grayish yellow silty fine to medium sand up to 4.0m and thereafter whitish' grey I yellowish grey weathered rock is observed up to 6.0 to l0.0m depth. Below this depth whitish grey I pinkish grey soft /rock! hard rock is observed up to the termination depth. The boreholes are terminated at 8.3m and 12.0m respectively from the existing ground level. During the time of investigation water table was encountered at an average of 4.0 m from the existing ground level.

CONCLUSIONS

The following conclusions and recommendations are given based on field and laboratory investigations.

I) The stratum up 4.5/6.0m depth is found to be loose to medium dense in nature.

2) The silt / clay present in the soil is found to be medium compressible in nature.

of 71


3) The silt / clay present in the soil is found to be medium plastic in nature.

4) During the time of investigation water table was encountered at an average of 4.0 m from the existing ground level.

RECOMMENDATIONS

The following recommendations are made based on the detailed investigation conducted and the conclusions drawn. I. The foundation for all structure shall be taken to a minimum depth of 3.0m below the

existing ground level.

2. Individual footing/raft foundation may be designed with the following allowable bearing pressure of, which gives a factor of safety of 3.0 against shear failure and for an allowable settlement of 25mm:

Depth, m S.B.C (t/m2) 3.0 22

4.5 25

6.0 32

3. The bottom of foundation shall be properly leveled and verified for loose pockets/weaker zones and if found, the same shall be replaced with lean concrete.

Alternatively

Bored cast-in-situ pile foundation is recommended based on load consideration. Piles shall be socketed into hard rock for at least 0.6 times the diameter of pile or 5 times the diameter in hard strata or weathered rock.

In cases of pile founded in a hard stratum the spacing will be governed by the competency of end bearing strata. The minimum spacing in such cases, shall be 2.5times the diameter of the shaft. In case pile resting on hard rock 2 times the diameter may be adopted. Piles deriving their bearing capacity mainly from the friction shall be sufficiently apart to ensure that the zones of soils from which piles derive their support do not overlap to such an extent that their bearing values are reduced. Generally spacing in such cases shall not be less than three times the diameter of the shaft.

For the design consideration (Design length of pile= 10.Om from existing ground) following allowable load carrying capacity of the piles may be considered. However actual load carrying capacity of pile may be arrived by conducting initial pile load test.
